From the pics in the Defender catalog it looks like the nav lights on the 16 are Aqua Signal 25 series . Is that right? To replace a lens it also looks like you have to buy the cover as well. Is there an LED replacement for the bulb? I recall some concerns with color and distance requirements with LED replacements but don't know where that stands.
Looked a little further on the nav light page and answered my LED question, red green replacement for $44. one watt vs ten.

Check this out, guy at work just bought bulbs from there, 25 bucks each (I think) I plan to order from there when I get more money......
I found it easier to buy the whole light and replace the entire fixture for like 25 bucks (or less)
about 50 bucks a light and youll have all new and LED to boot

It all comes back to me now, he said as he p_ssed into the wind. Nav lights are CG certified with the original type bulb but not with a different type even if its specs meets the color and distance requirements. So its a sure energy benefit vs a remote chance of a legal slam. With so many operators who are careless or worse, especially at night, its good to have your butt well covered.
